The stalagmite is a kind of speleothems able to provide climate information with an annual resolution and much longer bine span comparing to tree rings. Two aspects of annual banding of stalagmite have ho reported: the luminescent microbanding observed under a fluoromicroscope and the lamina Which is visible to the naked eye. Rainily, the authors have studied. stalagmites from Beijing Shihua Cave within the East Asian monsoon zone and found that, under the polarizing microscope, the transparent microbanding is also very pronounced The preliminary result shows that there existed about 1 131 continuously microbands at the upper part of the stalagmite-TS9501. Each microband, mostly Ans of micron in thickness, consists of tWo parts: the light zone at its bottom Which may be de posited from the "old water" which existed in the fissure pushed out by the initial rainfall in a year, and the dark zone on the top which may deposited from the "freSh water"which came from the covetal soil and contained more organic matter'The Shihua Cave was developed in Ordovician limestone. The stalagmite is about 200mm high and of column-shape. AMS14C dating suggests that the upper 45mm of the stalagmite has an age of not older than 2 000 years B.P. It is clear that the rhythm of each microbanding comparable to the fluctuation of the annual precipitation which possesses only one annual peak value in most years in the monsoon arm and changeS in a wide range similar to that of microbands. The authors have developed a time series according to the microbanding thickness and compared with the record of drought and flood drown from the historical documents of the last 522 years (from 1470 to 1992 yrA.D.) and the instrumental record of precipitation from 1951 to 1980yrA.D. (according to the data from National Climate Center). The coherence of there curves suggests once again that the microbanding is an annual deposition. Conequently, the light and dark parts for each band may reflect seasonal environmental hydrological changes.Baed on the thickness change data of the stalagmite-TS9501 the authors reconstructed tentatively an annual resolution climatic fluctuation curve of the last 1 130 years in Beijing area. The precipitation was at its highest in about 1080 yr A.D. and after that time it was decreasing to the lowest in about 1455yr A.D., then gradually increasing up to its highest in 1950' of mis century. The 136-year, 50-year, 16 - 18 -year, 11 -year and 5.8 -year climatic cycles are observed.
